Abstract: In order to improve the lump coal rate, According to CEMENTER coal seam geological condition and equipment selection, Aimed at the main factors influencing the lump coal rate in production: Screw drum of shearer parameters,The production process and Transfer point in the process of belt transportation reprint way has carried on the detailed study, According to the results after the implementation, The lump coal rate on the basis of the lump coal rate increased by 8 ~ 10%, Coal quality were fully guarantee, And mastered the more suitable for the Mr. Montier coal mine geological conditions of production process, To ensure the safety in production of orderly, Make the mine under the condition of the market downturn still can achieve good economic benefit. At the same time, the effective implementation of this technique in ordos region geological conditions improve the lump coal rate of technology research provides certain theoretical basis.

Key words: Drum of shearer parameters, The production process, Belt reprint way, Cycle to pressure control, Spiral chute, The lump coal rate.
